- <p>The release notes mention some bug-fixes, but are focused on
- new features and improvements to existing features log since
- <em class="small-caps">ncurses</em> 5.9 release.</p>
+ <h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
- <p>While the intent of the release is to provide a new stable
- ABI, there are other development activities which are summarized
- below.</p>
+ <p>There are several new features:</p>
<ul>
<li>
- <p>The original release plan, e.g., for "5.10" was to improve
- the MinGW port. Ultimately that was completed (wide-character
- support, mouse, etc), but was deferred to focus on termcap
- support and performance issues. Also, pinpointing the
- problems with <code>Console2</code> took a while.</p>
+ <p><a href=
+ "@HOMEPAGE@/man/form_field_opts.3x.html">O_EDGE_INSERT_STAY</a>
+ tells the form library to optionally delay cursor movement on
+ a field edge/boundary</p>
</li>
<li>
- <p>A review of termcap compatibility in 2011 led to several
- minor fixes in the library and improvements to utilities. To
- do this properly, a review of the various extent termcap
- implementations was needed.</p>
-
- <p>The <a href=
- "http://invisible-island.net/ncurses/tctest.html">termcap
- library checker (tctest)</a> (not part of <em class=
- "small-caps">ncurses</em>) was one result. A followup review
- of performance using <a href=
- "http://invisible-island.net/ncurses/ncurses-examples.html">ncurses-examples</a>
- in 2014 led to additional improvements.</p>
+ <p><a href=
+ "@HOMEPAGE@/man/form_field_opts.3x.html">O_INPUT_FIELD</a>
+ extension to form library allows a dynamic field to shrink if
+ the new limit is smaller than the current field size.</p>
</li>
<li>
- <p>Output buffering provided a further, but worthwhile
- distraction. A bug report in 2012 regarding the use of signal
- handlers in <em class="small-caps">ncurses</em>) pointed out
- <a href=
- "http://lists.gnu.org/archive/html/bug-ncurses/2012-07/msg00029.html">
- a problem</a> with the use of unsafe functions for handling
- <code>SIGTSTP</code>. Other signals could be addressed with
- workarounds; repairing <code>SIGTSTP</code> required a
- different approach. The solution required changing internal
- behavior of the library: how it handles output buffering.</p>
-
- <p>Now <em class="small-caps">ncurses</em> buffers its own
- output, independently of the standard output. A few
- applications relied upon the library's direct reuse of the
- standard output buffering; however that is
- <em>unspecified</em> behavior and has never been a
- recommended practice. Identifying these applications as well
- as refining the change to permit low-level applications to
- work consistently took time.</p>
- </li>
-
- <li>
- <p>Since the introduction of the experimental support for 256
- colors early in <a href=
- "http://invisible-island.net/ncurses/NEWS.html#t20050101">2005</a>
- (released in <a href=
- "http://invisible-island.net/ncurses/announce-5.5.html">ncurses
- 5.5</a>), there has been increased user interest. Almost all
- packagers continue providing the ncurses ABI 5 which cannot
- support 256 colors.</p>
- </li>
-
- <li>
- <p>Symbol versioning, or the lack of it in ncurses, is the
- main reason why packagers would be reluctant to add a new
- ncurses ABI.</p>
-
- <p>This release provides the new ABI along with
- script-generated lists of versioned symbols which can be used
- for both ABI 5 and 6 (with distinct names to keep the two
- separate). This took time to development, as reported in
+ <p>added <a href=

- <p>X/Open curses provides more than one initialization
- function:</p>
-
- <ul>
- <li><a href=
- "http://invisible-island.net/ncurses/man/curs_initscr.3x.html#h3-initscr">

- output</li>
-
- <li><a href=
- "http://invisible-island.net/ncurses/man/curs_terminfo.3x.html#h3-Initialization">
- setupterm</a> (the low-level function) accepts a parameter for
- the <em>file descriptor</em> of the output.</li>
+ <li>
+ <p>added <a href=
+ "@HOMEPAGE@/man/curs_trace.3x.html#h3-Functions">curses_trace</a>,
+ to replace trace().</p>
+ </li>
</ul>
- <p>They are documented in X/Open <em>as if</em>
- <code>initscr</code> calls <code>newterm</code> using
- <code>stdout</code> for output stream, and in turn
- <code>newterm</code> calls <code>setupterm</code> using
- <code>fileno(stdout)</code> for the file descriptor. As long as
- an implementation acts <em>as if</em> it does this, it conforms.
- In practice, implementations do what is implied. This creates a
- problem: the low-level <code>setupterm</code> function's file
- descriptor is unbuffered, while <code>newterm</code> implies
- buffered output. X/Open Curses says that all output is done
- through the file descriptor, and does not say how the output
- stream is actually used.</p>
-
- <p>Initially, <em class="small-caps">ncurses</em> used the file
- descriptor (obtained from the output stream passed to
- <code>newterm</code>) for changing the terminal modes, and relied
- upon the output parameter of <code>newterm</code> for buffered
- output. Later (to avoid using unsafe buffered I/O in signal
- handlers), <em class="small-caps">ncurses</em> was modified to
- use the file descriptor (unbuffered output) when cleaning up on
- receipt of a signal. Otherwise (when not handling a signal), it
- continued to use the buffered output.</p>
-
- <p>That approach worked reasonably well and as a side effect,
- using the same buffered output as an application might use for
- <code>printf</code> meant that no flushing was needed when
- switching between normal- and screen-modes.</p>
-
- <p>There were a couple of problems:</p>
+ <p>Additionally, to improve performance other changes (and
+ extensions) are provided in this release:</p>
<ul>
<li>
- <p>to get good performance, curses (not only <em class=
- "small-caps">ncurses</em>, but SVr4 curses in general) set an
- output buffer using <code>setbuf</code> or similar function.
- There is no standard (or portable) way to turn that output
- buffer off, and revert to line-buffering. The <code><a href=
- "http://invisible-island.net/ncurses/man/ncurses.3x.html#h3-NCURSES_NO_SETBUF">
- NCURSES_NO_SETBUF</a></code> environment variable did make it
- optional.</p>
+ <p>mouse decoding now handles shift/control/alt logic when
+ decoding xterm's 1006 mode</p>
</li>
<li>
- <p>to handle <code>SIGTSTP</code> (the “stop”
- signal), <em class="small-caps">ncurses</em> relied upon
- unsafe functions. That is, due to the complexity of the
- feature, it relied upon reusing existing functions which
- should not have been called via the signal handler.</p>
+ <p>ncurses now defines a limit for <a href=
+ "@HOMEPAGE@/man/curs_getstr.3x.html">wgetnstr</a>, <a href=
+ "@HOMEPAGE@/man/curs_get_wstr.3x.html">wgetn_wstr</a> when
+ length is negative or “too large”.</p>
</li>
- </ul>
-
- <p>Conveniently, solving the second problem (by making <em class=
- "small-caps">ncurses</em> do its <em>own</em> output buffering)
- also fixed the first one. But there were special cases to
- resolve: <a href=
- "http://invisible-island.net/ncurses/man/curs_terminfo.3x.html"><em>
- low-level</em></a> functions such as mvcur, putp, vidattr
- explicitly use the standard output. Those functions were reused
- internally, and required modification to distinguish whether they
- were used by the high-level or low-level interfaces.</p>
-
- <p>Finally, there may still be a few programs which should be
- modified to improve their portability, e.g., adding an</p>
-
- <blockquote>
- <pre class="code-block">
-fflush(stdout);
-</pre>
- </blockquote>
-
- <p>when switching from “<a href=
- "http://invisible-island.net/ncurses/man/curs_kernel.3x.html#h3-reset_prog_mode_-reset_shell_mode">shell</a>”
- mode to “<a href=
- "http://invisible-island.net/ncurses/man/curs_kernel.3x.html#h3-reset_prog_mode_-reset_shell_mode">program</a>”
- (curses) mode. Those are fairly rare because most programmers
- have learned not to mix <code>printf</code> and <code><a href=
- "http://invisible-island.net/ncurses/man/curs_printw.3x.html">printw</a></code>.</p>
-
- <h3><a name="h3-lib-versioning" id="h3-lib-versioning">Symbol
- versioning</a></h3>
-
- <p>This release introduces symbol-versioning to <em class=
- "small-caps">ncurses</em> because without it, the change of ABI
- would be less successful. A lengthy discussion will be presented
- in <a href=
- "http://invisible-island.net/ncurses/ncurses-mapsyms.html">Symbol
- versioning in <em class="small-caps">ncurses</em></a>. These
- notes summarize what has changed, and what can be done with the
- new release.</p>
-
- <p>Symbol-versioning allows the developers of a library to mark
- each public symbol (both data and functions) with an identifier
- denoting the library name and the version for which it was built.
- By doing this, users of the library have a way to help ensure
- that applications do not accidentally load an incompatible
- library. In addition, private symbols can be hidden entirely.</p>
-
- <p>This release provides sample files for the four principal
- configurations of <em class="small-caps">ncurses</em> libraries:
- <code>ncurses</code>, <code>ncursesw</code>,
- <code>ncursest</code> and <code>ncursestw</code>. Each sample is
- given in two forms:</p>
-
- <blockquote>
- <dl>
- <dt>“<code>.map</code>”</dt>
-
- <dd>These list all public symbols, together with version
- names.</dd>
-
- <dt>“<code>.sym</code>”</dt>
-
- <dd>These list all public symbols, without version
- names.</dd>
- </dl>
- </blockquote>
-
- <p>The sample files are <em>generated</em> by scripts which take
- into account a few special cases such as <a href=
- "http://invisible-island.net/ncurses/tack.html">tack</a> to omit
- many of the <em class="small-caps">ncurses</em> private symbols
- (beginning with “<code>_nc_</code>”). Here are
- counts of globals versus locals:</p>
-
- <blockquote>
- <table border="1" summary="Total global and local symbols">

- <p>Although only four sample configurations are presented, each
- is formed by merging symbols from several combinations of
- configure-script options, taking into account advice from
- downstream packagers. Because they are formed by merging, the
- sample files may list a symbol which is not in a given package.
- That is expected. The samples have been tested and are working
- with systems (such as Fedora, FreeBSD and Debian) which fully
- support this feature. There are other systems which do
- <em>not</em> support the feature, and a few (such as Solaris)
- which provide incomplete support.</p>

+ <h4><a name="h4-fixes-library" id="h4-fixes-library">Other
+ improvements</a></h4>
- <p>The new release has several improvements for performance and
- building. For instance:</p>
+ <p>These are revised features:</p>
<ul>
<li>
- <p>several files in ncurses- and progs-directories were
- modified to allow <code>const</code> data used in internal
- tables to be put by the linker into the readonly text
- segment.</p>
+ <p>used “<tt>const</tt>” in some prototypes
+ rather than <tt>NCURSES_CONST</tt> where X/Open Curses was
+ updated to do this, e.g., <tt>wscanw</tt>, <tt>newterm</tt>,
+ the terminfo interface. Also use “<tt>const</tt>”
+ for consistency in the termcap interface, which was withdrawn
+ by X/Open Curses in Issue 5 (2007). As of Issue 7, X/Open
+ Curses still lacks “<tt>const</tt>” for certain
+ return values, e.g., <a href=
+ "@HOMEPAGE@/man/curs_util.3x.html#h3-keyname_key_name">keyname</a>.</p>
</li>
<li>
- <p>various improvements were made to building the Ada95
- binding, both in simplifying the generated files as well as
- improving the way it uses <code>gnatmake</code></p>
+ <p>modified <a href=
+ "@HOMEPAGE@/man/curs_bkgd.3x.html#h3-bkgd"><tt>wbkgd</tt></a>
+ and <a href=
+ "@HOMEPAGE@/man/curs_bkgrnd.3x.html#h3-bkgrnd"><tt>wbkgrnd</tt></a>
+ to improve compatibility with SVr4 curses, changing the way
+ the window rendition is updated when the background character
+ is modified</p>
</li>
- </ul>
-
- <p>There are also new features in the libraries:</p>
-
- <ul>
- <li>added <a href=
- "http://invisible-island.net/ncurses/man/curs_util.3x.html#h3-use_tioctl">
- use_tioctl</a> function</li>
<li>
- <p>added <a href=
- "http://invisible-island.net/ncurses/man/curs_opaque.3x.html">
- wgetdelay</a> to retrieve _delay member of WINDOW if it
- happens to be opaque, e.g., in the pthread configuration.</p>
+ <p>improved terminfo write/read by modifying the fourth item
+ of the extended header to denote the number of valid strings
+ in the extended string table (see <a href=
+ "@HOMEPAGE@/man/term.5.html#h3-EXTENDED-STORAGE-FORMAT">term(5)</a>).</p>
</li>
<li>
- <p>added <a href=
- "http://invisible-island.net/ncurses/man/curs_attr.3x.html#h2-PORTABILITY">
- A_ITALIC</a> extension.</p>
+ <p>modified the initialization checks for mouse so that the
+ <a href=
+ "/ncurses/terminfo.src.html#tic-xterm_sm_1006"><tt>xterm+sm+1006</tt></a>
+ block will work with terminal descriptions not mentioning
+ <em>xterm</em>.</p>
</li>
+ </ul>
+ <p>These were done to limit or ultimately deprecate features:</p>
+
+ <ul>
<li>
- <p>added form library extension <a href=
- "http://invisible-island.net/ncurses/man/form_field_opts.3x.html">
- O_DYNAMIC_JUSTIFY</a> option which can be used to override
- the different treatment of justification for static versus
- dynamic fields .</p>
+ <p>deprecated <a href=
+ "@HOMEPAGE@/NEWS.html#t970831">safe-sprintf</a>, since the
+ <tt>vsnprintf</tt> function, which does what was needed, was
+ standardized long ago.</p>
</li>
<li>
- <p>rewrote <a href=
- "http://invisible-island.net/ncurses/man/curs_util.3x.html#h3-putwin_getwin">
- putwin</a> and <a href=
- "http://invisible-island.net/ncurses/man/curs_util.3x.html#h3-putwin_getwin">
- getwin</a>, making an extended version which is capable of
- reading screen-dumps between the wide/normal <em class=
- "small-caps">ncurses</em> configurations. These are text
- files, except for a <em>magic</em> code at the beginning:</p>
-
- <blockquote>
- <pre class="code-block">
-0 string \210\210 Screen-dump (ncurses)
-</pre>
- </blockquote>
+ <p>marked <a href=
+ "@HOMEPAGE@/man/curs_printw.3x.html#h2-PORTABILITY"><tt>vwprintw</tt></a>
+ and <tt>vwscanw</tt> as deprecated; recommend using <a href=
+ "@HOMEPAGE@/man/curs_printw.3x.html"><tt>vw_printw</tt></a>
+ and <tt>vw_scanw</tt>, respectively.</p>
</li>
<li>
- <p>several changes to mouse support include:</p>
-
- <ul>
- <li>added decoder for xterm SGR 1006 mouse mode.</li>
-
- <li>added experimental support for
- “<code>%u</code>” format to terminfo.</li>
+ <p>added deprecation warnings for internal functions called
+ by older versions of <a href=
+ "@HOMEPAGE@/tack.html">tack</a>.</p>
+ </li>
- <li>improved behavior of wheel-mice for xterm protocol:
- noting that there are only button-presses for buttons
- “4” and “5”, so there is no need to
- wait to combine events into double-clicks .</li>
- </ul>
+ <li>
+ <p>removed unused <tt>_nc_import_termtype2</tt> function.</p>
</li>
</ul>
- <p>There are a few new configure options dealing with library
- customization:</p>
+ <p>These are improvements to existing features:</p>
<ul>
<li>
- <p>add “<code>--enable-ext-putwin</code>”
- configure option to turn on the extended putwin/getwin. By
- default, this is enabled for ABI 6 and disabled with ABI
- 5.</p>
+ <p>check parameter of <a href=
+ "@HOMEPAGE@/man/curs_threads.3x.html">set_escdelay</a>,
+ return ERR if negative.</p>
</li>
<li>
- <p>add “<code>--enable-string-hacks</code>”
- option to control whether strlcat and strlcpy may be used.
- Because <em class="small-caps">ncurses</em> already does the
- requisite buffer-limit checks, this feature is mainly of
- interest to quiet compiler-warnings on a few systems.</p>
+ <p>check parameter of <a href=
+ "@HOMEPAGE@/man/curs_threads.3x.html">set_tabsize</a>, return
+ ERR if not greater than zero</p>
</li>
<li>
- <p>add configure option
- “<code>--with-tparm-arg</code>” to allow <a href=
- "http://invisible-island.net/ncurses/man/curs_terminfo.3x.html#h3-Formatting-Output">
- tparm</a>'s parameters to be something more likely to be the
- same size as a pointer, e.g., <code>intptr_t</code> (again,
- the default is set for ABI 6).</p>
+ <p>correct a status-check in _nc_read_tic_entry() so that if
+ reading a hex/b64 <a href=
+ "@HOMEPAGE@/man/ncurses.3x.html#h3-TERMINFO"><tt>$TERMINFO</tt></a>,
+ and the <a href=

</li>
- </ul>
- <h3><a name="h3-programs" id="h3-programs">Program

+ </li>
- <h4><a name="h4-utilities" id="h4-utilities">Utilities</a></h4>
-
- <p>Most of the termcap-related changes based on development of
- <a href="http://invisible-island.net/ncurses/tctest.html">tctest
- (termcap library checker)</a> are implemented in the tic and
- infocmp programs rather than affecting the library. As noted in
- the <a href=
- "http://invisible-island.net/ncurses/tctest.html#my-better-translation">
- discussion</a> of <code>tctest</code>, <em class=
- "small-caps">ncurses</em>'s ability to translate between terminfo
- and termcap formats has been improved at different times, but
- subject to feedback from "real" termcap users. There are very few
- of those. Nowadays, virtually all <em>termcap</em> users are
- using <em class="small-caps">ncurses</em> (or NetBSD, with its
- own terminfo library) and their programs are actually using
- terminfo rather than termcap data.</p>
-
- <p>Still, there are a few. A comment about the translation of the
- ASCII <code>NUL</code> character prompted a review:</p>
+ <li>
+ <p>move macro for <a href=
+ "@HOMEPAGE@/man/curs_touch.3x.html"><tt>is_linetouched</tt></a>
+ inside <strong><tt>NCURSES_NOMACROS</tt></strong>
+ <em><tt>ifndef</tt></em>.</p>
+ </li>
- <ul>
<li>
- <p>Both terminfo and termcap store string capabilities as
- <code>NUL</code>-terminated strings.</p>
+ <p>use <tt>_nc_copy_termtype2</tt> rather than direct
+ assignment in <a href=
+ "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Initialization">setupterm</a>,
+ in case it is called repeatedly using fallback terminfo
+ descriptions</p>
</li>
<li>
- <p>In terminfo, a <code>\0</code> in a terminal description
- is stored as <code>\200</code>.</p>
+ <p>improve workaround for Solaris wcwidth versus line-drawing
+ characters</p>
</li>
<li>
- <p>There are no (known) terminals which would behave
- differently when sent <code>\0</code> or
- <code>\200</code>.</p>
+ <p>add checks in <a href=
+ "@HOMEPAGE@/man/resizeterm.3x.html"><tt>repair_subwindows</tt></a>
+ to keep the current position and scroll-margins inside the
+ resized subwindow.</p>
</li>
<li>
- <p>When translating to terminfo format (or displaying a
- printable version of an entry using infocmp), <em class=
- "small-caps">ncurses</em> shows <code>\200</code> as
- <code>\0</code>.</p>
+ <p>correct a buffer-limit in <tt>write_entry.c</tt> for
+ systems that use caseless filenames.</p>
</li>
<li>
- <p>It has done this since 1998 (quoting from the NEWS
- file):</p>
+ <p>improved build-time utility <em>report_offsets</em>:</p>
- <blockquote>
- <pre class="code-block">
-<a href=
-"http://invisible-island.net/ncurses/NEWS.html#t980103">980103</a>
-...
- + modify _nc_tic_expand() to generate \0 rather than \200.
-...
- + correct translation of terminfo "^@", to \200, like \0.
-</pre>
- </blockquote>
+ <ul>
+ <li>
+ <p>add categories, e.g., "w" for wide-character, "t" for
+ threads to make the report more readable. Reorganized the
+ structures reported to make the categories more
+ apparent.</p>
+ </li>
+
+ <li>
+ <p>add <tt>NCURSES_GLOBALS</tt> and
+ <tt>NCURSES_PRESCREEN</tt> to report to show how similar
+ the different <em>libtinfo</em> configurations are.</p>
+ </li>
+ </ul>
</li>
<li>
- <p>However, the <code>_nc_tic_expand</code> function (which
- optionally produces terminfo or termcap format) did not
- address this special case for termcap. Even the later 4.4BSD
- <a href=
- "https://svnweb.freebsd.org/base/head/lib/libc/gen/getcap.c?revision=244092&view=markup#l784">
- cgetstr</a> interprets a <code>\0</code> literally, ending
- <em>that</em> string (rather than using the terminfo
- improvement).</p>
+ <p>modified some header files to ensure that those include
+ necessary files except for the previously-documented
+ cases</p>
</li>
- </ul>
-
- <p>As a result of the review, several improvements were made to
- <em class="small-caps">ncurses</em> translation to/from termcap
- format — and improving the checks made in tic for
- consistency of entries. Most of these are not of general
- interest, except for two new command-line options for tic and
- infocmp:</p>
- <ul>
<li>
- <p>the “<code>-0</code>” option generates
- termcap/terminfo source on a single line.</p>
+ <p>added some traces in initialization to show whether a
+ fallback entry is used.</p>
</li>
<li>
- <p>the “<code>-K</code>” option provides stricter
- BSD-compatibility for termcap output.</p>
+ <p>made minor optimization to reduce calls to
+ _nc_reserve_pairs</p>
</li>
</ul>
- <p>Other user-visible improvements and new features include:</p>
+ <p>These are corrections to existing features:</p>
<ul>
<li>
- <p>added “<code>-D</code>” option to tic and
- infocmp, to show the database locations that it could
- use.</p>
+ <p>fix a special case in <tt>PutAttrChar</tt> where a cell is
+ marked as alternate-character set, but the terminal does not
+ actually support the given graphic character. This would
+ happen in an older terminal such as <em>vt52</em>, which
+ lacks most line-drawing capability.</p>
+ </li>
+
+ <li>
+ <p>corrected flag for "seq" method of db 1.8.5 interface,
+ needed by toe on some of the BSDs.</p>
</li>
<li>
- <p>added “<code>-s</code>” option to toe, to sort
- its output.</p>
+ <p>modify comparison in make_hash.c to correct a special case
+ in collision handling for Caps-hpux11</p>
</li>
<li>
- <p>extended “<code>-c</code>” and
- “<code>-n</code>” options of infocmp to allow
- comparing more than two entries.</p>
+ <p>add extended_slk_color{,_sp} symbols to the appropriate
+ package/*.{map,sym} files</p>
</li>
<li>
- <p>modified toe's report when “<code>-a</code>”
- and “<code>-s</code>” options are combined, to
- add a column showing which entries belong to a given
- database.</p>
+ <p>modify lib_setup to avoid calling pthread_self() without
+ first verifying that the address is valid, i.e., for weak
+ symbols</p>
</li>
<li>
- <p>modified the clear program to take into account the
- “<code>E3</code>” extended capability to clear
- the terminal's scrollback buffer.</p>
+ <p>add a couple of broken-linker symbols to the list of
+ versioned symbols to help with link-time optimization versus
+ weak symbols.</p>

+
+ <p>Along with the library and utilities, improvements were made
+ to the <a href=
+ "@HOMEPAGE@/ncurses-examples.html">ncurses-examples</a>. Most of
+ this activity aimed at improving the test-packages. A few changes
+ are more generally useful, e.g., for the main ncurses
+ test-program, and for analyzing traces using the
+ <em>tracemunch</em> script:</p>
<ul>
<li>
- <p>added scripts for building dpkg and rpm test-packages</p>
+ <p>improve recovery from error when reading command-character
+ in <tt>test/ncurses.c</tt>, showing the relevant error
+ message and not exiting on EINTR.</p>
</li>
<li>
- <p>modified the hanoi test-program to show the minimum number
- of moves possible for the given number of tiles.</p>
+ <p>improve <em>tracemunch</em>, by keeping track of
+ <tt>TERMINAL*</tt> values, and if tracing was first turned on
+ after initialization, attempt to show distinct screen, window
+ and terminal names anyway.</p>
</li>
<li>
- <p>modified the knight test-program to show the number of
- choices possible for each position in automove option, e.g.,
- to allow user to follow Warnsdorff's rule to solve the
- puzzle.</p>
+ <p>modify <em>tracemunch</em> to accept filename parameters
+ in addition to use as a pipe/filter.</p>
</li>
- </ul>
-
- <h3><a name="h3-database" id="h3-database">Terminal
- database</a></h3>
- <p>This release provides improvements to tic's
- “<code>-c</code>” checking option, which was used for
- example to</p>
+ <li>
+ <p>update <em>tracemunch</em> to work with <em>perl
+ 5.26.2</em>, which changed the rules for escaping regular
+ expressions.</p>
+ </li>
- <ul>
<li>
- <p>make <code>sgr</code> in several entries agree with other
- caps.</p>
+ <p>add some checks in <em>tracemunch</em> for undefined
+ variables.</p>
</li>
<li>
- <p>correct padding in some entries where earlier versions had
- miscounted the number of octal digits.</p>
+ <p>modify <tt>TurnOn</tt>/<tt>TurnOff</tt> macros (in
+ lib_vidattr.c and lib_vid_attr.c) to avoid expansion of
+ “<tt>CUR</tt>” in trace.</p>

</li>
<li>
- <p><code>TS</code> is used in the <a href=

- xterm+sl</a> building block to help deprecate the misuse of
- <code>tsl</code> for xterm's title-string.</p>
+ <p>add “<tt>@</tt>” command to test/ncurses
+ F-test, to allow rapid jump to different character pages.</p>
</li>
<li>
- <p><code>XT</code> is used in some terminfo entries to
- improve usefulness for other applications than screen, which
- would like to pretend that xterm's title is a
- status-line.</p>
+ <p>added enum, regex examples to test/demo_forms</p>
</li>
<li>
- <p><code>xm</code> is used in examples <a href=

</li>
- </ul>

-
- <p>As usual, this release</p>
-
- <ul>
<li>
- <p>improves documentation by describing new features,</p>
+ <p>corrected pathname used in Ada95 sample programs for
+ <tt>explain.txt</tt>, to work with test-packages, and used an
+ awk script to split the resulting pathname when it would be
+ too long for a single line.</p>
</li>
<li>
- <p>attempts to improve the description of features which
- users have found confusing</p>
+ <p>ignore interrupted system-call in test/ncurses's
+ command-line, e.g., if the terminal were resized.</p>
</li>
<li>
- <p>fills in overlooked descriptions of features which were
- described in the <a href=
- "http://invisible-island.net/ncurses/NEWS.html">NEWS</a> file
- but treated sketchily in manual pages.</p>
+ <p>improved ifdef's for <tt>TABSIZE</tt> variable, to help
+ with AIX/HPUX ports.</p>
</li>
</ul>
- <p>In addition, the mechanism for producing HTML versions of the
- documentation has been improved:</p>
+ <h3><a name="h3-database" id="h3-database">Terminal database</a></h3>

- ncurses</em> 5.8</a>.</p>
+ <p>While there were many bugs fixed during development of ncurses
+ 6.2, only a few (the reason for this release) were both important
+ and interesting. Most of the bug-fixes were for local issues
+ which did not affect compatibility across releases. Since those
+ are detailed in the NEWS file no elaboration is needed here.</p>
- <p>The MinGW port can be readily cross-compiled:</p>
+ <p>The interesting bugs were in tic/infocmp's handling of
+ user-defined capabilities. These were not recent bugs. Initially
+ it was a simple problem:</p>
<ul>
- <li>
- <p>modified configure script to allow creating dll's for
- MinGW when cross-compiling.</p>
- </li>
+ <li>The user-defined capabilities can be any type (boolean,
+ number or string), but once given a type all uses of the name
+ must conform to that type—unless some special support for
+ a particular multi-typed name is built into ncurses.</li>
<li>
- <p>enforced Windows-style path-separator if
- cross-compiling,</p>
- </li>
+ <p>One of simpleterm's contributors copied some definitions
+ for using <em>tmux</em>'s user-defined capabilities in
+ <a href=
+ "https://git.suckless.org/st/commit/06f8cf8ca87a81db15816658c40b2afcd1ad5332.html">
+ late in 2016</a>.</p>
- <li>
- <p>added scripts for test-builds of cross-compiled packages
- for ncurses6 to MinGW.</p>
+ <blockquote>
+ <pre class="demo-name">
+diff --git a/st.info b/st.info

+ </blockquote>
</li>
<li>
- <p>added pc-files to the MinGW cross-compiling
- test-packages.</p>
+ <p>Later, in (referring to a version from <a href=
+ "https://git.suckless.org/st/commit/c0882f2ed1d7a2dd0fa2efa52157e6fc6fde3652.html">
+ mid-2017</a>), a user asked to have it updated in
+ ncurses.</p>
</li>
<li>
- <p>added script for building test-packages of binaries
- cross-compiled to MinGW using NSIS.</p>
+ <p>However, it had an error from the change in late 2016. The
+ terminal description made what <em>tmux</em> expected to be
+ <strong>string</strong> actually a
+ <strong>boolean</strong>.</p>
+
+ <p>Over the years, there were problems with each of
+ simpleterm's terminal descriptions. I repaired those, and
+ usually dealt with the problem.</p>
</li>
<li>
- <p>added <code>nc_mingw.h</code> to installed headers for
- MinGW port; this is needed for cross-compiling <a href=
- "http://invisible-island.net/ncurses/ncurses-examples.html">ncurses-examples</a>.</p>
+ <p>The difference in this case was that when compiling the
+ terminal database, <em>tic</em> may have in memory the
+ definitions for more than one terminal description (so that
+ it can resolve “<tt>use=</tt>” clauses). Seeing
+ two different types for the same name, in certain situations
+ it would incorrectly merge the symbol tables for the two
+ terminal descriptions.</p>
</li>
<li>
- <p>added test-packages for cross-compiling ncurses-examples
- using the MinGW test-packages.</p>
+ <p>On simpleterm's side, their bug was finally fixed in
+ <a href=
+ "https://git.suckless.org/st/commit/83866428de031300eab03fbb116bcf7d2b1d4f60.html">
+ late 2019</a>, three years after the bug was created.</p>
</li>
</ul>
- <p>The MinGW-specific Windows driver accounts for several
- changes:</p>
+ <p>For ncurses, the elapsed time to fix this bug was less than
+ three years. Someone reported a problem with the terminal
+ description a few weeks after releasing ncurses 6.1 (in <a href=
+ "https://github.com/tmux/tmux/issues/1264">tmux #1264</a>), and
+ the terminal description was updated that week (ncurses patch
+ <a href="@HOMEPAGE@/NEWS.html#t20180224">20180224</a>):</p>
+
+ <blockquote>
+ <pre class="demo-name">
+20180224
+ + modify _nc_resolve_uses2() to detect incompatible types when merging
+ a "use=" clause of extended capabilities. The problem was seen in a
+ defective terminfo integrated from simpleterm sources in 20171111,
+ compounded by repair in 20180121.
+ + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+</pre>
+ </blockquote>
+
+ <p>The larger part of that change added a check to prevent a
+ simple merge of terminal descriptions where the same user-defined
+ name was used with different types. But it raised some
+ questions:</p>
<ul>
<li>
- <p>wide-character display is made usable by replacing MinGW's
- non-working <code>wcrtomb</code> and <code>wctomb</code>
- functions.</p>
+ <p>Was there a reliable way to manage terminal descriptions
+ which used the same extended name in different ways?</p>
</li>
<li>
- <p>implemented some display features: <a href=
- "http://invisible-island.net/ncurses/man/curs_beep.3x.html">beep</a>,
- <a href=
- "http://invisible-island.net/ncurses/man/curs_beep.3x.html">flash</a>,
- <a href=
- "http://invisible-island.net/ncurses/man/curs_kernel.3x.html#h3-curs_set">
- curs_set</a>.</p>
+ <p>Should ncurses provide a registry of well-known extended
+ names, with their types?</p>
</li>
+ </ul>
- <li>
- <p>the driver handles repainting on endwin/refresh
- combination.</p>
- </li>
+ <p>Since the correction to <a href=
+ "@HOMEPAGE@/ncurses.html#download_database"><tt>terminfo.src</tt></a>
+ could have been readily adopted by packagers, there was nothing
+ more to be done from ncurses' standpoint on that part. But
+ improving ncurses to prevent issues like that is the reason for
+ making a release.</p>
- <li>
- <p>modified treatment of <code>TERM</code> variable for MinGW
- port to allow explicit use of the Windows console driver by
- checking if <code>$TERM</code> is set to
- “<code>#win32console</code>” or an abbreviation
- of that.</p>
- </li>
+ <p>Nothing more (constructive) was mentioned with regard to
+ simpleterm. But a few problems were found in the handling of
+ user-defined capabilities:</p>
+ <ul>
<li>
- <p>the Windows driver also matches the special
- <code>TERM</code> value “unknown”</p>
- </li>
+ <p>Forward-references to user-defined capabilities in a
+ “<tt>use=</tt>” clause did not allocate new data
+ for each use. In <em>tic</em>, successive compilation of
+ terminal entries could add user-defined capabilities to the
+ wrong terminal entry.</p>
- <li>
- <p>the driver now returns characters for special keys, (like
- <code>ansi.sys</code> does), when keypad mode is off, rather
- than returning nothing at all.</p>
+ <p>This was not noticed before, since xterm's terminal
+ descriptions were the main users of the feature, and almost
+ all of the uses of the building-blocks which contained
+ user-defined capabilities were backward-references.</p>
</li>
<li>
- <p>the driver checks a new environment variable <a href=
- "http://invisible-island.net/ncurses/man/ncurses.3x.html#h3-NCURSES_CONSOLE2">
- NCURSES_CONSOLE2</a> to optionally work around a deficiency
- in <code>Console2</code> (and its descendent
- <code>ConsoleZ</code>) which hang when an application creates
- a console buffer.</p>
+ <p>There is one (documented) case where ncurses 6.1 supports
+ a user-defined capability that could be any type (i.e.,
+ “RGB”). The check added in February 2018 to guard
+ against mismatches did not handle all of the combinations
+ needed.</p>
</li>
</ul>
- <p>Finally, there are other improvements:</p>
+ <p>Both of these issues dated from the original implementation of
+ user-defined capabilities. Fixing them does not change the
+ terminal database, but a older <em>tic</em> without the fixes
+ will not be able to handle terminfo sources which rely upon those
+ fixes. Starting in June 2019, the download link for the terminfo
+ source file was capped at that date. The development sources have
+ an up-to-date copy of the file, for people with a legitimate need
+ for it.</p>
+
+ <p>The “<tt>-c</tt>” (check) option of <em>tic</em>
+ is not very useful if it cannot offer advice on parameters needed
+ for user-defined capabilities. The various <em>Caps</em> files
+ were reorganized to reduce redundancy, and in the common portion
+ (<a href=
+ "https://github.com/ThomasDickey/ncurses-snapshots/blob/master/include/Caps-ncurses">Caps-ncurses</a>),
+ a registry of user-defined capabilities is provided for use by
+ <em>tic</em>. While users can still define their own custom
+ capabilities, <em>tic</em> will not offer any advice when their
+ parameters do not match.</p>
+
+ <p>In ncurses 6.2, <em>tic</em> makes a special check to allow
+ any type for <em>RGB</em>, but its being able to do this relies
+ upon fixes made in the ncurses library in mid-2019.</p>

+ <h3><a name="h3-portability" id="h3-portability">Portability</a></h3>
+ <p>Many of the portability changes are implemented via the
+ configure script:</p>
+
+ <ul>
<li>
- <p>work around a bug introduced by <a href=
- "http://stackoverflow.com/questions/20877689/gcc-4-8-1-minggw-d-option-does-not-work-as-usual">
- gcc 4.8.1</a> in MinGW which breaks "trace" feature.</p>
+ <p>ignore <a href=
+ "/ncurses/man/ncurses.3x.html#h3-TERMINFO"><tt>$TERMINFO</tt></a>
+ as a default value in configure script if it came from the
+ <tt>infocmp</tt> <strong><tt>-Q</tt></strong> option.</p>
</li>
<li>
- <p>add a driver-name method to each of the drivers.</p>
+ <p>distinguish gcc from icc and clang when the
+ <tt>--enable-warnings</tt> option is not used, to avoid
+ unnecessary warnings about unrecognized inline options</p>
</li>
- </ul>
-
- <h4><a name="h4-port-systems" id="h4-port-systems">Other
- ports</a></h4>
- <p>These changes affect certain platforms (ports):</p>
-
- <ul>
<li>
- <p>the configure script knows how to build shared libraries
- with DragonFlyBSD and Interix.</p>
+ <p>consistently prepend new libraries as they are found
+ during configuration, rather than relying upon the linker to
+ resolve order dependencies of libraries.</p>
</li>
<li>
- <p>support for AIX shared libraries is improved, tested with
- AIX 5.3, 6.1 and 7.1 with both gcc 4.2.4 and cc:</p>
+ <p>modified configure scripts to reduce relinking/ranlib
+ during library install :</p>
<ul>
- <li>
- <p>the shared-library suffix for AIX 5 and 6 is now
- ".so"</p>
- </li>
-
- <li>
- <p>the <code>-brtl</code> option is used with AIX 5-7; it
- is needed to link with the shared libraries.</p>
- </li>
+ <li>use “<tt>install -p</tt>” when available,
+ to avoid need for ranlib of static libraries.</li>
+
+ <li>scripts which use
+ “<tt>--disable-relink</tt>;” add a 1-second
+ sleep to work around tools which use whole-second
+ timestamps, e.g., in <tt>utime</tt> rather than the actual
+ file system resolution.</li>
</ul>
</li>
<li>
- <p>the configure <code>--enable-pc-files</code> option takes
- into account the <a href=
- "http://linux.die.net/man/1/pkg-config"><code>PKG_CONFIG_PATH</code></a>
- variable.</p>
- </li>
+ <p id="getenv-check">add configure check for <a href=
+ "#getenv-fixes"><tt>getenv</tt></a> to work around
+ implementation shown in Emscripten which overwrites the
+ previous return value on each call.</p>
- <li>
- <p>the configure option <code>--with-pkg-config-libdir</code>
- provides control over the actual directory into which
- pc-files are installed.</p>
+ <p>Use that to optionally suppress <tt>START_TRACE</tt>
+ macro, whose call to <tt>getenv</tt> may not work
+ properly</p>
</li>
<li>
- <p>the build scripts add explicit -ltinfo, etc., to the
- generated ".pc" file when <code>ld</code> option
- “<code>--as-needed</code>” is used, or when
- ncurses and tinfo are installed without using rpath.</p>
+ <p>change target configure level for <tt>_XOPEN_SOURCE</tt>
+ to 600 to address use of <tt>vsscanf</tt> and
+ <tt>setenv</tt>.</p>
</li>
<li>
- <p>the configure script disallows conflicting options
- “<code>--with-termlib</code>” and
- “<code>--enable-term-driver</code>”.</p>
+ <p>reduce use of <tt>_GNU_SOURCE</tt> for current glibc where
+ <tt>_DEFAULT_SOURCE</tt> combines with
+ <tt>_XOPEN_SOURCE</tt></p>
+
+ <p>Allow for Cygwin's newlib when checking for the
+ _DEFAULT_SOURCE symbol.</p>
+
+ <p>MidnightBSD is now checked for the
+ <tt>_XOPEN_SOURCE</tt>-related definitions.</p>
</li>
<li>
- <p>the check for missing c++ compiler to work when no error
- is reported, and no variables set is improved (see note for
- <a href=
- "http://invisible-island.net/ncurses/NEWS.html#t20021206">20021206</a>).</p>
+ <p>If the check for <tt>va_copy</tt> or <tt>__va_copy</tt>
+ fails,</p>
+
+ <ul>
+ <li>configure now tries copying the pointers for
+ <tt>va_list</tt>, or as an array.</li>
+
+ <li>alternatively, it checks for
+ <tt>__builtin_va_copy</tt>(), which could be used with AIX
+ <tt>xlc</tt> in <em>c89</em> mode.</li>
+ </ul>
</li>
<li>
- <p>the misc/gen_edit.sh script selects a "linux" entry which
- works with the current kernel rather than assuming it is
- always "linux3.0"</p>
+ <p>several changes to support a port to Ultrix 3.1:</p>
+
+ <ul>
+ <li>check if "b" binary feature of fopen works</li>
+
+ <li>check for missing feature of locale.h</li>
+
+ <li>add fallback for strstr() in test-programs</li>
+
+ <li>add fallback for STDOUT_FILENO in test-programs</li>
+ </ul>
</li>
<li>
- <p>the test/configure script makes it simpler to override
- names of curses-related libraries, to help with linking with
- pdcurses in MinGW environment.</p>
+ <p>The <em>test/configure</em> script (used for <a href=
+ "/ncurses/ncurses-examples.html"><em>ncurses-examples</em></a>)
+ is improved:</p>
+
+ <ul>
+ <li>work around non-ncurses termcap.h file, e.g., in
+ Slackware.</li>
+
+ <li>check for <a href=
+ "/ncurses/man/curs_variables.3x.html#h3-TABSIZE"><tt>TABSIZE</tt></a>
+ variable.</li>
+
+ <li>checks for the X11/Intrinsic.h header, accommodate
+ recent MacOS changes which largely emptied
+ <tt>/usr/include</tt>.</li>
+ </ul>
</li>
+ </ul>
+
+ <p>Here are some of the other portability fixes:</p>
+ <ul>
<li>
- <p>the configure-script/ifdef's allow the BSD OLD_TTY feature
- to be suppressed if the type of <code>ospeed</code> is
- configured using the option <code>--with-ospeed</code> to not
- be a <code>short</code>. By default, it is a
- <code>short</code> for termcap-compatibility.</p>
+ <p>added dummy "check" rule in top-level and test-Makefile to
+ simplify building test-packages for ArchLinux.</p>
</li>
<li>
- <p>the MKlib_gen.sh script works around a recent change in
- gcc 5 (released <a href=
- "https://gcc.gnu.org/gcc-5/">mid-2015</a>) which essentially
- emits multiple <code>#line</code> statements for the same
- position in a file.</p>
+ <p>dropped library-dependency on psapi for MinGW port, since
+ win_driver.c defines <tt>PSAPI_VERSION</tt> to 2, making it
+ use <tt>GetProcessImageFileName</tt> from kernel32.dll</p>
</li>
<li>
- <p>the configure script works with Minix3.2 (see <a href=
- "http://invisible-island.net/autoconf/portability-test.html">note</a>
- on portability)</p>
+ <p>made build-fixes for configuration using --program-suffix
+ with Ada95, noticed with MacOS but applicable to other
+ platforms without libpanelw, etc.</p>
</li>
<li>
- <p>OS/2 redux:</p>
-
- <ul>
- <li>
- <p>the configure script supports OS/2 kLIBC.</p>
- </li>
-
- <li>
- <p>the <code>--with-lib-prefix</code> option allows
- configuring for old/new flavors of OS/2 EMX.</p>
- </li>
- </ul>
+ <p>modified ncurses/Makefile.in to fix a case where
+ Debian/testing changes to the ld --as-needed configuration
+ broke ncurses-examples test packages.</p>
</li>
<li>
- <p>improved configure-script checks for
- <code>_XOPEN_SOURCE</code>:</p>
-
- <ul>
- <li>
- <p>the definition works starting with Solaris 10.</p>
- </li>
-
- <li>
- <p>the definition is suppressed for IRIX64, since its
- header files have a conflict versus
- <code>_SGI_SOURCE</code>.</p>
- </li>
- </ul>
+ <p>used <tt>_WIN32</tt>/<tt>_WIN64</tt> in preference to
+ <tt>__MINGW32__</tt>/<tt>__MINGW64__</tt> symbols to simplify
+ building with Microsoft Visual C++, since the former are
+ defined in both compiler configurations.</p>
</li>
</ul>
